' 12 Claims.

This invention relates to and has for an object the provision of acombination siphon bottle and carbonator, or what may be termed a selfcarbonating siphon bottle, wherein upon introduction of liquid and gasthereto from sources under pressure, the liquid will be automatically,thoroughly saturated with the gas within the bottle during suchintroduction, whereby the bottle is therefore subject to being quickly,easily and conveniently charged or recharged.

Another object of, this invention is to provide a self carbonatingsiphon bottle of the character described which is equipped with valveintaking means adapted to be engaged with a filling fountain from whichseparate'streams of liquid and gas are directed through said valve meansinto the bottle upon the occasion of positioning the bottle in apredetermined manner relative to or upon said fountain or over saidfountain whereby quick and convenient filling of the bottle adjacent thepoint of its use, such, for example, as upon a shelf or serving bar, ismade possible. At the same time, a thorough carbonating action takesplace within the bottle during the introducition of the liquid and gasthereto.

I have shown inthe accompanying drawings a preferred form of combinedsiphon bottle and carbonator embodying my invention, subject, however,to modification, within the scope of the appended claims, withoutdeparting from the spirit of my invention.

One embodiment of the combined siphon bottle and carbonator of thisinvention, as shown in the accompanying drawings, comprises a siphonbottle I equipped with the usual siphoning or dispensing head 8 and anautomatic carbonating and intaking means 9, which latter is adapted to1937, Serial No. 159,613 (Cl. 226-62) be engaged with a filling fountainIn. As here shown, the fountain I8 is mounted upon a shelf, serving bar,or like support ll so that the bottle may be stood upon or over thefountain in such manner that the means 9 will engage with the fountainto establish a filling connection therewith, and when disengaged fromthe fountain will cause the bottleto close as well as the fountain.Inasmuch as the fountain I8 is adapted to charge separate streams ofliquid and gas into the bottle, it is connected with pressure sources ofliquid and gas not shown by means of pipe lines l2 and I3, respectively,and by a control valve ll in the liquid line l2 and a pressureregulating valve I5 01 any suitable form in the line l3, the pressure ofgas discharging through the fountain may be regulated, in considerationof the liquid pressure.

The siphoning head 8 comprises the usual body portion l6, having adischarge spout I I and equipped with a spring loaded, normally closedvalve l8, operated by means of a handle H. De-

pending from the body into the neck of the bottle is a valve chamber I8-supporting a siphon tube 20, the lower intake end 2| of which isdisposed adjacent the concavo-convex bottom wall 22. Pressure of gas onthe liquid in the bottle causes an upward fiow thereof through the tube20, past the valve I8 when open, and out through the spout I! in theusual manner.

In accordance with this invention, the automatic carbonating and liquidand gas intaking means 9 is arranged so that a stream of gas underpressure is introduced adjacent the lower end of the bottle, whereas astream of liquid under pressure is introduced through an atomizer orspray device 23 adjacent the upper end of the bottle. This atomizercauses a finely divided liquid and gas may be quickly and convenientlyintroduced into the bottle by the mere placing of the bottle in apredetermined position with respect to the filling fountain, as, forexample, the standing of the bottle over the fountain, makes possibleadvantages and conveniences and the saving of time in the initial andrefilling operations of siphon bottles constructed in accordance withthis invention.

One form of the combined automatic carbonating and liquid and gasintaking means of this invention which I may use comprises a tubularvalve body 24 mounted in an opening 25 formed in the center of thebottom 22 of the bottle and secured at such point by means of the nut 28and cooperating flange 21, together with suitable packing or sealingmeans. Siidably supported within the valve body 24 is an upright liquidinjection tube 23 terminating adjacent the upper end of the bottle inthe atomizer 23. At its lower end, this tube is normally closed by anupwardly opening check valve 34 mounted in a housing 3|, which has asocket portion 32 at its lower end adapted for reception of the liquiddischarge spout 33 of the fountain i3. Y when this spout is engaged inthe socket 32, the pressure of the liquld.will open the valve 30 and theliquid will pass upwardly through the tube 23 and out through theatomizer 23, the valve closing automatically upon removal of the bottlefrom the fountain.

The gas discharges into the bore of the valve body 24 and passesupwardly through the grooves 34 and 35, formed respectively in thehousing 3| and body 24. The uppermost grooves 35 open into a valve seat35 controlled by a valve 31 carried by the tube 29. The valve 31 isnormally held seated by the spring 38 mounted in the body 24 andparticularly shown in Fig. 4, and this spring likewise holds thesocketed end 32 in extended position. With this arrangement, it is seenthat when the said socketed end engages the spout 33 of the fountain ID,the gas admission valve 31 in the bottle is open to permit introductionof gas into the .bottle, and that this valve will automatically closeupon detaching the bottle from the fountain.

The fountain I 0, as here shown, comprises a sectional tubular body 33adapted to be secured to the shelf or serving bar I! by means of thethreaded fittings 33 and 40. The fitting 33 is extended above the shelfor support il in the form of a tubular coupling member 4|, havinginterrupted threads 42 interiorly thereof and adapted to cooperate withsimilar threads 43 provided on a tubular extension 44 of the body 24.The member 44 is arranged to fit within the coupling 4| when the bottleis positioned for refilling, and upon appropriate turning of the bottle,a quick, detachable, mechanical joint of the bottle with the fountainmay be eflected.

The liquid discharge spout 33 of the fountain i0 is slidably positionedwithin the bore of the body 33 so that its upper end is extended intothe tubular coupling 4|. The lower end of the spout I3 is slidablewithin the bore 43 of a closure 44 which defines the valve chamber 45 atthe lower end of the body 38. This closure 44 is provided with anannular valve seat 46 surrounding the bore 43 andadapted to be engagedby a valve 41 normally held seated by a spring 48. The valve 41 has astem 43 slidably supported in a plug 53, to which plug the liquid pipeline I2 is connected by any suitable means. Liquid entering the borethrough the plug will flow through inclined outlets 5| into the chamber45, and if the valve 41 is unseated, will enter the spout 33 through thelateral openings in the lower end of said pout.

The gas discharge from the fountain I0 is controlled by an inwardly heckvalve within a refrigerator or ice 53 opening responsive to gas pressurefrom pipe line l3 to permit gas to flow into a chamber 44 in the body38. The upper end of this chamber has an opening 55 which is groovedvertically and affords a, sliding support for the spout 33 whilepermitting discharge of gas through the grooves thereof. The gas outletthus formed around the spout 33, that is between the spout and theopening 55, is controlled by a valve 53 on the spout 33. A spring 51normally holds the spout 33 in ."Dpermost position whereby the valve 33is seated to close the gas outlet. In this position of the spout, thelateral intake openings I2 in the lower end thereof are closed by thewall of the bore 43, as shown in Fig. 6.

It is now seen that when the bottle is positioned over the fountain, asshown in Figs. 1 and 4, with the socket 32 receiving the spout 33. thelatter will be depressed, while, at the same time, the tubular member 29will be elevated. Depression of the spout 33 allows the gas to pass fromthe chamber 54 through the opening 55 into the body 24, and through thegrooves 34 and 35 into the bottle, the valve 31 having been unseated bythe raising of the tubular member 29. At the same time, the valve 41 isunseated by the depressed spout 33, which latter has its lateral intakeopenings then exposed to the chamber 45, as shown in Fig. 4. Liquidunder pressure in said chamber will then pass upwardly through the spout33, check valve 30 and tubular member 23 so as to be discharged throughthe atomizer 23 in the form of a flne whirling mist which will showerdownwardly and be intimately admixed with and saturated by the gasarising in the bottom.

It ,will be noted that the combined siphon bottle and carbonator of thisinvention provides for the complete saturation of the liquid with thegas within the bottle during the introduction of the liquid into thebottle. In the charging operation, the gas enters the bottle first andthereafter, as the liquid is discharged, through the atomizer as a finemist-like spray, it becomes effectively saturated with gas. When a bodyof liquid has collected in the bottle, the gas arising through it willfurther saturate the liquid to provide for a more thorough carbonatingaction. It is important to note that the filling fountain forintroducing liquid and gas into the siphon bottle is so constructed thatit may be conveniently placed box so that upon placing the siphon bottlein the box over the fountain, in accordance with this invention, thecharging and carbonating action will take place automatically while thebottle is thus standing in the refrigerator.
